Testers Needed for New RTAI Packages

What does "xrandr" say ?
If that does not list your screen resolution, it most probably will not work. Been a long time since i messed with that.

xrandr shows 1024 x 768, 800 x 600 and 640 x 480

I think that is because it reverts back to the vesa driver because of not being able to run the frambuffer driver.

You have to enable "source code" repositories in the "software sources" from the main menu>administration.

I looked in Menu>Administration and I don't see that option. The closest thing I could find is this.


I am getting this error and I could find this/these in Synaptic.



I also saw this when debuild -uc -us finished running.

I was following the instructions for "Debian 10 LinuxCNC" at www.gnipsel.com/linuxcnc/uspace/debian10-emc.html
I may try Linux Mint 19.1 using a spare SSD I have and see how that goes.

I loaded Linux Mint 19.2, RTAI 4.14.148 and 2.8.0~Pre1

uname -a shows:
Linux X3CNC 4.14.148-rtai-amd64 #2 SMP PREEMPT Sat Nov 9 16:29:10 GMT 2019 x86_64 x86_64 x86_64 GNU/Linux

I am getting an error when starting LinuxCNC of "in 'estop-latch.1.ok-out' does not exist" so I tried to run halshow pins aand I get this:

john@X3CNC:~$ halshow
RTAPI: ERROR: could not open shared memory (No such file or directory)
HAL: ERROR: could not initialize RTAPI
halcmd: hal_init() failed: -22
NOTE: 'rtapi' kernel module must be loaded
Segmentation fault (core dumped)
john@X3CNC:~$

Does this indicate what I did wrong?

Thanks
John

To run halshow you need to be linked in to the running realtime.

So, with linuxCNC running:

halcmd -kf
loadusr halshow

Or, simpler

halcmd -kf
show pins

Or, even:

halcmd show pins

I reloaded everything. I have good latency of 19100. But when I start LinuxCNC I get an error of:
insmod: ERROR: could not insert module /usr/realtime-4.14.148-rtai-amd65/modules/rtai_hal.ko: File exists 8456

Kernel message information:
/usr/lib/tcltk/linuxcnc/show_erros.tcl:
dmesg: read kernel buffer failed: Operation not permitted

dmesg requires root privlege on this system.

Now, what I think I am seeing in this. The error after the ERROR label and a secondary error of not being able to call dmesg to display the dmesg info.

I did a find and as it says "/usr/realtime-4.14.148-rtai-amd64/modules/rtai_hal.ko" does exist.
No what?

Thanks
John

Try sudo dmesg

Did you "sudo make setuid" after compiling LinuxCNC?
(Did you compile LinuxCNC?)

I did not compile LinuxCNC. I used the files from www.linuxcnc.org/temp . I did have some success. I can now start LinuxCNC. I am now working on getting the .hal file for my P4S pendant converted. I'm sure there are still some issues with my LinuxCNC .hal & .ini files but at least I was able to start it and get a list of pin names.

Is there a list that shows the old and new pin names side by side?

One other thing I need to do is to get it to boot into the rtai kernel by default. I think there is a grub manager program for that.

Thanks
John

Just remove all other kernels, leaving only the RTAI kernel.

The internet suggests that the command will configure grub to boot into the last-selected kernel.
(there are other suggestions, but that seems the simplest, if it works)
